Frequently Asked Questions
How long does a metal roof last?
Standing seam metal roofs last 40-70 years with proper installation. Corrugated metal panels typically last 25-40 years. Metal roofs withstand high winds, are fire-resistant, and reflect heat. They cost more upfront but often pay for themselves in longevity and energy savings.
Standing seam vs corrugated metal roofing?
Standing seam uses concealed fasteners (hidden clips) making it more weather-tight and long-lasting, but more expensive. Corrugated and R-panel use exposed fasteners which are cheaper to install but may require fastener replacement over time. Standing seam is preferred for residential; corrugated for agricultural and commercial buildings.
